I am not sure of the significance of the dots on both sides of the triangle on the 5002 dial, the triangle and the dots being a bit more centralised than on the 5004/5009 or on my 3878 Spitfire Chrono. There, the dots serve as minute markers for 59 and 1. Quite cute.Kind regards,Paul

What you do may not be so important, but it is very important that you do it well. (my variation of a saying by Gandhi)

To the best of my knowledge, the Ref 431 B-Uhr was the first pilot watch to have in its dial design the triangle/double dot combination at 12. It is fair to assume the Luftwaffe designers intended the dial to be easily readable in black-out during night missions, and found this feature met the objectives.I don't think there is any significance to IWC using the double dot on its modern pilot watches, other than emulating the pilot watches of a past, when watches were essential for accurate navigation.
